CVE-2025-4638

一、漏洞信息
 漏洞编号：[CVE-2025-4638](https://nvd.nist.gov/vuln/detail/CVE-2025-4638)
 漏洞归属组件：[zlib](https://gitee.com/src-openeuler/zlib)
 漏洞归属的版本：1.2.13,1.3.1
 CVSS V3.0分值：
  BaseScore：N/A None
  Vector：CVSS：3.0/
 漏洞简述：
  A vulnerability exists in the inftrees.c component of the zlib library, which is bundled within the PointCloudLibrary (PCL). This issue may allow context-dependent attackers to cause undefined behavior by exploiting improper pointer arithmetic.Since version 1.14.0, PCL by default uses a zlib installation from the system, unless the user sets WITH_SYSTEM_ZLIB=FALSE. So this potential vulnerability is only relevant if the PCL version is older than 1.14.0 or the user specifically requests to not use the system zlib.
